3 Claims. 1

This invention comprises apparatus and method for cargo handling tofacilitate the removal of cargo from a boat or ships hold and totransfer it to a dock or pier as well as to lift cargo from a dock anddeposit it in a hold of a ship with a minimum expenditure of time andlabor.

Other objects of this invention are to provide apparatus, a part ofwhich is superposed over a ships hold and suitably anchored topositively, prevent displacement during the unloading or loading cycles,the apparatus being adjustable to conform to the size and contour of thehold; to include in the apparatus a monorail for carrying a powdered ormanually operated hoist dolly, the monorail being equipped with safetydevices to prevent movement of the dolly beyond predetermined raillimits; to provide means for permitting independent adjustment of themonorail; and to provide apparatus constructed in accordance with theteaching of this invention, which may be placed in position over andremoved by the ships crane without the use of extraneous mechanism.

A further object of the invention is to provide a method for loading andunloading ships wherein a monorail rig is superposed over the shipshold, the monorail extending transversely of the ship in order totransport the ships cargo over the side of the ship for transference toa pier-carried monorail which preferably extends at right angles to theship-carried monorail, the monorail on the pier being equipped withcargo transporting apparatus.

Other objects of the invention will be apparent from the followingdescription of the present proferred form of the invention taken inconnection with the accompanying drawings, wherein:

Figure l is a perspective view of an apparatus for cargo handlingconstructed in accordance with the present invention illustrating itsapplication to a boat and adjacent pier;

Figure 2 is a detail enlarged fragmentary top plan view of a frame jointas employed in the present invention;

Figure 3 is a transverse sectional view of the same taken on the line3;--3 of Figure 2;

Figure 4 is a detail fragmentary perspective view of the connectionclamp for the rig frame and a rig carried monorail; and

Figure 5 is a detail fragmentary perspective view of one of the rigcarried anchoring straps illustrating its application to the boat.

In order to illustrate the application of this invention, a boat 6 isshown in Figure 1 of the drawings which includes a hold I, thepassageway or alley to which is indicated at 8. Figure 1 also, forpurposes of illustrating the application of the invention, shows a pier9 which runs in parallel relation to the boat 6 and is equipped with amonorail [0 supported by stanchions H. The monorail carries apparatusgenerally designated l2 for transporting cargo on the pier in an obviousmanner.

The apparatus of the present invention includes a rig generallydesignated l3, the rig in the present instance consisting of arectangular skeleton extensible frame l4 supported on deck cariedstandards IE. The frame, composed of interengageable beams, is providedat each side and at each end with a joint 16 which permits telescopicconnection of adjacent parts of the frame. The joint includes bolts I1and jam nuts it to secure the adjacent slidable terminals of the frameparts together as illustrated advantageously in Figures 2 and 3.

The rig I3 is adapted to be anchored on the deck of the boat 6immediately over the hold I and for this purpose clamping straps l9 areemployed. Two straps L) are employed, one being engaged with each of thetwo parallel standards P5. The upper end of each strap is secured to itsstandard, as indicated at 29. At a point just below the locus ofsecurement, the strap is bent outwardly, as indicated at 2|, and thestrap continues downwardly to a point appreciably below the bottom ofthe standard 15 and correspondingly below the alley 8 on the inside ofthe latter. The lower end of each strap is bifurcated, as indicated at22, the branches of the bifurcation straddling a bolt 23 which extendsfrom and is carried by a permanent part 24 of the deck. of the boat. Bythis arrangement, as advantageously illustrated in Figure 5, the rig ispositively secured from casual displacement at the side of the rigopposite to that over which or beyond which the cargo is transported. Inorder to support transporting means for the boats cargo, a boat monorail25 is employed, the monorail being pendently carried by the frame of therig l3. In order to clamp the monorail to the frame, a suitable clampingassembly, generally designated 26, is used. Each of the clamps includestwin base plates 21, the inner ends of which are offset to provideflanges 28 which are slidable beneath the top run of the monorail 25.One terminal of each of the base plates is reduced and bent upwardly atright angles to provide a lug 29 which is adapted to embrace the innerface of the frame portion of the rig [3 as shown in Figure l. Theclamping assembly 26 also includes a spanner plate 30 which extendsacross the plates 21 above the depressed flanges 23. The plate 30 hassuperposed thereon a key plate 3| the latter, in conjunction with thespanner plate 311, being secured to the base plates 21 by bolts 32. Theclamping assembly 25 is detachably secured, through the medium of thebolts 32 to the monorail 25 and parallel sides of the frame M.

The monorail 25 is equipped with cargo handling apparatus generallydesignated 33 which may support cargo 34 as shown in Figure 1. Themonorail .25 is of a length to permit the free end thereof to span thedistance between the boat 6 and pier 9, the free terminal preferablyoverlapping an intermediate portion of the pier carried monorail [0. Bythis arrangement cargo removed from the ships hold is transported overthe side of the boat to the pier and manually transferred from the boatcarried cargo handling apparatus 33 to the pier carried cargo handlingapparatus [2. The reverse procedure is followed when loading the boat.

In accordance with the teaching of the present invention, a rig of verysimple construction may be positioned in close proximity to the alley orships hold by the ships crane. The frame may be expanded or contractedto adjust the rig to the dimensions of the alley. Correspondingly, theframe may be anchored to the deck of the boat at one side of the alleyin a manner already herein described. In view of the completeadjustability of the rig it adapts itself for any dimensional variation.The rig is positively anchored to the deck and if desired, its standards15 may have pressure plates 35 inserted therebetween and the deck. Whennot in use, the rig may be dismanteled and stored in a relatively smallplace.

Although a preferred apparatus and method is shown and described herein,weare aware that various changes may be made within. the scope of theclaims hereto appended.

What we claim is:

1. In combination with a ship including a deck with an alley leading tothe ships hold, apparatus to facilitate lifting of cargo from the holdand lowering cargo into the latter comprising a rig mounted on th deck,the rig embodying supporting standards positioned around said alley, apair of straps, one engaged with each of the standards at one side ofthe rig, the lower ends of the straps being laterally offset for slidingengagement over the ships alley and bifurcated at a point ap- 4preciably below the top of the latter and means secured to a permanentpart of the deck for engagement with each bifurcation to prevent casualdisplacement at the side of the rig opposite to that over which orbeyond which the cargo is transported.

2. A device for handling ships cargo comprising a rig adapted to beanchored on the deck of the ship above the ships hold, the rigcomprising a rectangular extensible frame, each side of the frameincluding a joint, means for securing the joint to prevent relativemovement of the frame parts, the rig also including vertical standardswhich pend from the corners of the frame and are engaged with the shipsdeck adjacent the hold, a strap engaged with each of two parallelstandards, the lower ends of the straps extending into the ships holdand secured to a permanent part of the deck of the ship to preventcasual displacement of the rig, and a monorail one end of which issecured to the undersurface of the rectangular frame, the opposite endprojecting beyond the side of the ship, said monorail being adapted forthe transportation of cargo to and standards positioned around saidalley, ex-

tensible beams mounted on the standards and spanning the latter, meansfor transporting cargo to and from the rig including a monorail carrier,and a clamp assembly for securing the monorail to a, parallel pair ofsaid beams, said assembly permitting a sliding movement of the monorailtherein when the beams are extended in the direction of the monorail.
